Gel Permeation Chromatography of Heparins

Thrombosis and Haemostasis, 1980
SummaryGel permeation chromatography of heparins using water as solvent has recently been used to obtain fractions for biological investigation. We find that heparin fractions obtained in this way are not, necessarily, differentiated simply on a molecular size basis as has been alleged.

Gel matrices for scanning gel chromatography

Biophysical Chemistry, 1979
I have examined the light-scattering behavior of a number of gel matrices used in gel filtration chromatography. The angular dependence of light scattering by Sephadexes is consistent with treatment of the particles as large scattering particles with a low refractive index increment (mu).

Bacteriophage purification by gel chromatography

Analytical Biochemistry, 1981
Abstract We have developed an inexpensive procedure for bacteriophage purification suitable for small- and medium-scale preparations (up to one liter of lysate). The method consists of precipitation with polyethylene glycol 6000 and gel chromatography on a Bio-Gel A-5m column. The purity of the phage preparation is comparable to that obtained by CsCl

Gel chromatography of carbohydrates on polysaccharide gel

Journal of Polymer Science: Polymer Symposia, 1980
AbstractLiquid chromatographies of high and low‐molecular carbohydrates and polyethyleneglycols of different molecular masses were studied on porous microspherical cellulose. Dependence of the distribution coefficients of polymer molecules on molecular mass was determined.

Fluorinated gels for gel permeation chromatography

Die Makromolekulare Chemie, 1993
AbstractThe aim of these investigations was the development of stationary phases for GPC compatible with fluorinated solvents. The properties of crosslinked copolymers of 4‐(2‐heptafluoropropoxy‐1, 2,2‐trifluoroethoxy)styrene (1) were investigated in dependence of the mode of synthesis. Divinylbenzene (DVB) was used as crosslinking agent.

Gel Chromatography

Angewandte Chemie International Edition in English, 1970
AbstractGel chromatography can be regarded as a network‐limited partitioning of substances. The theory of this method and the preparation and properties of various gel systems are reviewed. Optimization of the method is illustrated for the separation of oligomers.

Determination of the structure of agarose gels by gel chromatography

Biochimica et Biophysica Acta (BBA) - General Subjects, 1967
Abstract Well-characterized fractions of the synthetic polysaccharide Ficoll have been chromatographed on columns of pearl-condensed agarose gels of concentrations between 2 and 8%. The results agree with the theory that the Ficoll is sterically excluded from the gel, which is made up of a random three-dimensional network of long fibers.

The determination of myoglobin by gel chromatography

Analytical Biochemistry, 1978
Abstract The method recently described for the determination of haemoglobin in ovine muscles (1) has now been modified for the measurement of myoglobin. Evidence is presented here for the validity of using it for myoglobin determination in muscles of the rat, pig, sheep, and ox.

Resins and gels for chromatography

Journal of Chromatography A, 1970
Abstract Ion exchangers and gels for chromatography synthesized by the authors are decribed. Resins and gels for chromatography have been prepared based on copolymers of styrene and p - or m divinylbenzene. They are characterized by their high purity, homogeneity of granular composition, high mechanical strength and stability, and the ...

Chromatography of glycogens on agarose gels

Journal of Chromatography A, 1973
Abstract The chromatographic behavior of several glycogens on the agarose gels Sepharose 2B and Sepharose 4B has been investigated. These are shown to be convenient media for examination of the polydispersity and relative molecular weights of different glycogens.
